No one knows except the Father
Acts 1
In the former treatise, O Theophilus, I have given an account of all that Jesus began both to do and teach
2 until the day in which He was taken up, after He had given commandments through the Holy Ghost unto the apostles, whom He had chosen.
3 To these also He showed Himself alive after His passion by many infallible proofs, being seen by them forty days, and speaking of the things pertaining to the Kingdom of God.
4 And being assembled together with them, He commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, “which,” saith He, “ye have heard from Me;
5 for John truly baptized with water, but ye shall be baptized with the Holy Ghost not many days hence.”
6 When they therefore had come together, they asked of Him, saying, “Lord, wilt Thou at this time restore again the kingdom to Israel?”
7
And He said unto them, “It is not for you to know the times or the seasons which the Father hath put in His own power.
Jesus did tell us we can see the signs before He comes a second time
That we can observe those, means we are still on the earth up until the end
v22, refer to 2 Thessalonians 2 about the signs and wonder
Mark 13
19 For in those days shall be affliction such as was not from the beginning of the creation which God created until this time, neither shall be.
20 And except that the Lord had shortened those days, no flesh should be saved; but for the elect’s sake, whom He hath chosen, He hath shortened the days.
21 And then if any man shall say to you, ‘Lo, here is Christ!’ or, ‘Lo, He is there!’ believe him not;
22
for false christs and false prophets shall rise, and shall show signs and wonders to seduce, if it were possible, even the elect.
23 But take ye heed; behold, I have foretold you all things.
24 “But in those days, after that tribulation, ‘the sun shall be darkened, and the moon shall not give her light,
25 and the stars of heaven shall fall, and the powers that are in heaven shall be shaken.’
26 And then shall they see the Son of Man coming in the clouds with great power and glory.
27 And then shall He send His angels and shall gather together His elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven.
28 “Now learn a parable of the fig tree: When her branch is yet tender and putteth forth leaves, ye know that summer is near.
29 So ye in like manner, when ye shall see these things come to pass, know that it is nigh, even at the doors.
30 Verily I say unto you, that this generation shall not pass till all these things be done.
31 Heaven and earth shall pass away, but My words shall not pass away.
32 But of that day and that hour knoweth no man — no, not the angels who are in Heaven, neither the Son, but only the Father.
33 “Take ye heed, watch and pray; for ye know not when the time is.
34 For the Son of Man is as a man taking a far journey, who left his house and gave authority to his servants, and to every man his work, and commanded the doorkeeper to watch.
35 Watch ye therefore, for ye know not when the Master of the house cometh — at evening, or at midnight, or at the cockcrowing, or in the morning —
36 lest coming suddenly, He find you sleeping.
37 And what I say unto you, I say unto all: Watch!”
